- The Graph: Used for indexing and querying blockchain data efficiently. The Subgraph allows you to fetch detailed cityindex data easily. You can view the subgraph here.
- OnchainKit: Build your onchain apps with ready-to-use React components and Typescript utilities. The onchainkit gives you access to coinbase wallet and also allows for gasless fee with paymaster.
- Base: The platform is deployed on the Base network, a Layer 2 scaling solution for Ethereum that offers lower transaction costs and faster confirmations. Base was chosen for its scalability, making it ideal for frequent transactions. You can view a sample transaction on Base here.
